LV4 Lubricator Valves
The LV4 lubricator valve is a high-performance, surface-controlled, tubing-retrievable isolation barrier valve that is used as part of a downhole lubricator system. The valve provides a means of isolating well pressure in tubing strings where it has been deployed. Application of hydraulic pressure to the tool via dual control lines will operate the valve open or closed.
Traditionally well intervention string lengths are limited to the length of lubricator that can be stacked on top of the production tree. The addition of a LV4 lubricator valve extends these possibilities by placing the swab valve within the tubing string.
- Can be used in conjunction with the tubing-retrievable safety valve (TRSV) to form part of a well suspension system
- Allows through-tubing deployment of long length assemblies using intervention methods without killing the well
Typical applications include deployment of long TCP guns/straddle assemblies and bottomhole pressure/temperature instruments.
